As the stepper motor manufacturing industry competition intensifying, domestic outstanding stepper motor manufacturing enterprises more and more emphasis on industry market research, especially for industrial development environment and product the in-depth study of the buyer. Because of this, a large number of domestic excellent stepper motor brand rapid rise, gradually become the best stepper motor manufacturing industry. stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller. are usually for the permanent magnet motor rotor, when current flows through the stator winding of the stator winding is a vector field. The magnetic field can drive the rotor rotating an Angle, make a pair of rotor magnetic field direction in line with the stator magnetic field direction. When the vector magnetic field of the stator rotating an Angle. Also as the rotor magnetic field to turn an Angle. For every input electrical impulses, a rotary Angle of motor before further. Its output angular displacement is proportional to the input pulse count, speed is proportional to the pulse frequency. Changing the order of the winding current, the motor will be reversed. So the available control pulse number, frequency and various phase winding of the motor power in order to control the step motor rotation. with the development of science and technology, automation industry promotion between demands for motor products, to meet the quality and function of the basic conditions, on the basis of more products can achieve integration, functional, motor development to enterprise, occupies a place in the fierce competition, it is necessary to change, and always adhere to innovation, Shanghai four macro motor will walk in the forefront of the motor industry. Shanghai four small macro motor stepper motor development in the direction of the integration, automation industry is complied with international requirements for electrical products. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
